The Net::DSN::SEC suite provides the resource records that are needed for DNSSEC (RFC 4033, 4034 and 4035). In addition the DLV RR, a clone of the DS RR is supported (RFC 4431) It also provides support for SIG0. That later is useful for dynamic updates using key-pairs. RSA and DSA crypto routines are supported. For details see Net::DNS::RR::RRSIG, Net::DNS::RR::DNSKEY, Net::DNS::RR::NSEC, Net::DNS::RR:DS, Net::DNS::RR::DLV, and see Net::DNS::RR::SIG and Net::DNS::RR::KEY for the use with SIG0. Net::DNS contains all needed hooks to load the Net::DNS::SEC extensions when they are available. See Net::DNS for general help. WWW: http://search.cpan.org/dist/Net-DNS-SEC/
